The HP12 webinar teaches the technician the procedures used in determining compressor,

reversing valve, and metering device malfunctions:

1. Key Diagnostic Indicators

•  Are some indicators more important than others?

2. Metering Device Malfunctions

•  Does it make a difference in my diagnostics if I am working with a TXV versus a

                     Fixed Metering Device?

•  How does the metering device malfunction?

3. Compressor Malfunctions

•  How do you know for sure the compressor has malfunctioned?
•  What is the discharge line temperature used for?
•  What is a refrigerant enthalpy diagram used for?

4. Reversing Valve Malfunctions

•  Does the reversing valve always show a ΔT if it has malfunctioned?
•  Does suction superheat drop to 0° to 3° if the reversing valve malfunctions?

5. Service Call #1 (How to diagnose Compressor related issues.)

•  Low Capacity, High SST, and Low SCT.

6. Service Call #2 (How to diagnose Reversing Valve related issues.)

•  Low Capacity, High SST, and Low SCT.

7. Service Call #3 (How to diagnose metering device related issues.)

•  Low Capacity, High SST, and Low SCT.
